As an aside, I went to the Art Gallery of Ontario not too long ago with a friend. I thoroughly enjoyed exploring the "Drama and Desire" exhibit. Everyday I try to do an activity that doesn't distractions or involve messages and/or advertisements being thrown at me. These activities allow me to think, reflect. For once I am not bombarded by the thoughts/ideas of others. Examples of activities that may help you to just think may include going to art galleries (on special occasions), cooking/baking, writing in a journal, yoga, sodoku or crossword puzzles, cleaning (for some!), gardening, walking, meditating, hiking, running, painting, and drinking or eating without anything in front of you but a mug or plate of good food.
